Ethanol production from oil palm empty fruit bunch fiber prepared through pretreatment with sodium hydroxide under optimized conditions
Alkali pretreatment of oil palm empty fruit bunch (OPEFB) using sodium hydroxide (NaOH) was optimized by varying substrate concentration, alkali loading, temperature, and time. A Central Composite Design (CCD) based on the Box–Wilson factorial design was applied to determine conditions that maximized cellulose and hemi...
